lock BUICK SKYLARK 1993 Workshop Manual

0 It’s below freezing outside and most trips are less
than
10 miles (16 km).
0 The engine is at low speed most of the time (as in
door-to-door delivery, or in stop-and-go traffic).
0 You tow a trailer often.
0 Most trips are through dusty places.
If any one
of these is true for your vehicle, then you
need to change your oil and filter every
3,000 miles (5
000 km) or 3 months -- whichever comes first.
If none of them is true, change the oil every 7,500 miles
(12
500 km) or 12 months -- whichever comes first.
Change the filter at the first oil change and at every
other oil change after that.
Engine Block Heater: An engine block heater can be a
big help if you have to park outside in very cold weather, -20
F (-29 C) or colder. If your vehicle has
this option, see “Engine Block Heater.” in the Index.
What to Do with Used Oil:
I sed engine oil contains things that have caused
skin cancer in laboratory animals. Don’t let used
oil stay on your skin for very long. Clean your
skin and nails with soap and water,
or a good
hand cleaner. Wash
or properly throw away
c-othing
or rags containing used engine oil.
Used oil can be a real threat to the environment. Don’t
ever dispose of it by pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle it by taking it to a place that collects used
oil. If
you have a problem propeily disposing of your used oil,
ask your dealer, a service station or a local recycling center for help.

Headlights
The headlight wiring is protected by a circuit breaker in
the fuseblock. An electrical overload will cause the
lights to go on and
off, or in some cases to remain off. If
this happens, have your headlight wiring checked right
away.
Windshield Wipers
. The windshield wiper motor is protected by a circuit
breaker and a fuse. If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools.
If
the overload is caused by some electrical problem and
not snow, etc., be sure to get
it fixed. ,
Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power
windows and other power accessories. When the current
load is too heavy, the circuit breaker opens and closes,
protecting the circuit until the problem is fixed or goes
away.

Inspection
Throttle
Linkage Inspection
WHAT SHOULD BE DONE
hspect the front and rear suspension
and steering system for damaged,
loose or missing parts, signs of wear,
or lack of lubrication. Inspect the
power steering lines and hoses for
proper hookup, binding, leaks, cracks, chafing, etc. Clean and then
inspect the drive axle boot seals for
damage, tears or leakage. Replace
seals
if necessary.
Inspect the complete exhaust system. Inspect the body near the
exhaust system. Look for broken,
damaged, missing or out-of-position
parts as well as open seams, holes,
loose connections,
or other
conditions which could cause a heat
build-up in the floor pan or could let
exhaust fumes into the vehicle. See
“Engine Exhaust” in the Index.
Inspect the throttle linkage for interference or binding, and for
damaged or missing parts. Replace
parts as needed.

Brake System
Inspection
WHAT SHOULD BE DONE
Inspect the complete system. Inspect
brake
lines and hoses for proper
hookup, binding, leaks, cracks, chafing,
etc.
Inspect disc brake pads for wear
and rotors for swrface condition.
Also
inspect Qwn brake linings for wear and
cracks. Inspect other brake
parts
including drums, wheel cylinders,
calipers parking brake, etc. The parking
brake is self-adjusting and no manual adjustment
is required. You may need
to have your brakes inspected more often
if your driving habits or
conditions result in frequent braking.
NOTE: A low brake fluid level can
indicate worn disc brake pads which
may
need to be serviced. Also, if the
brake system warning light stays on or
comes on, something may
be wrong
with the brake system. See “Brake System
Warning Light” in the Index. If
your anti-lock brake system warning
light stays
on, comes on or flashes,
something may
be wrong with the
anti-lock brake system. See “Anti-Lock
